Bz1073903: Fix EAP_HOME server and path problems

Fixed the following issues:
Some instructions to start the folder were missing the `bin` directory in the path.
Where 2 servers are needed, removed the `_SERVER` from the path, so it's now `EAP_HOME_1` and `EAP_HOME_2` instead of `EAP_HOME_SERVER_1` and `EAP_HOME_SERVER_2`.
Some quickstart appended the `_1` even though there was only 1 server.
